A real good idea, a pleasure to share this book with my 5 year old son (who's after him for months!) Then go discover the places presented to ... Paris! Only downside, the quality of the illustrations: what strange quadrages! Why cut the Arc de Triomphe? Often I find them a bit truncated monuments and suddenly my son a little difficult to imagine those he does not know, or recognize when we are in Paris. Just a shame ...
